Filed: 1975-09-09
Abstract: 1480711 Concrete shuttering C I WILLIAMS 9 Sept 1975 [20 Sept 1974] 37115/75 Heading E1S In a method of casting large concrete structures, employing apparatus described and claimed in U.K. Specification No. 1436640, the time at which any particular pour should be made is determined in part by establishing the "vibration limit" for the preceding pour, making the new pour before the limit, and vibrating the concrete sufficiently to weld the preceding layer with the new layer. The vibration limit is said to coincide with the time at which an initial set takes place, which is in turn defined as the "elapsed time, after initial contact of cement and water, required   for the mortar sieved from the concrete to reach a penetration resistance of 500 p.s.i." The method employed is otherwise as disclosed in U.K. Specification 1436400.

In a method of manufacturing a semi-conductor device, having a relatively high resistivity N type region 6 between two relatively low resistivity P-type regions 4, 5, which extend inwardly from opposed major surfaces 16, 17 of the device, the peripheral edge of the device between rigid contact members secured to the major surfaces has material removed by abrasion so that the edge meets the major surfaces at the rigid members. This peripheral edge is so shaped that where it meets the PN junctions it forms with them an acute angle A on the side of the higher resistivity material. This angle is preferably 20-70 degrees inclusive. The abrasion is performed by sand-blasting, or by the use of an abrasive tool, or by use of a tool fed with an abrasive slurry. The contact member is of aluminium, gold, an alloy of these, or molybdenum.

A current supply network 11 for the photo-diode may be arranged as an integrated circuit, as also is an output amplifier 12 and a laser power source 13 for a lamp (not shown) positioned over the active medium. The laser amplifier is pulse operated in synchronism with a pulsed incident beam 1. The active medium 15, Fig. 3, is mounted on a carrier body 4 by a layer of adhesive material 14, and its cross-section is reduced by removing parts 16 and 17, e.g. by etching. A layer of transparent material 18 is applied over the active medium, this layer and the adhesive layer having a lower refractive index than that of the active medium to prevent loss of transmitted light.

Abstract: 906,831. Making electrical conductors. REYNOLDS METALS CO. Nov. 16, 1959, No. 38814/59. Class 83 (2). [Also in Groups XXXV and XXXVI] A flat-strip conductor, especially suitable for electrical coils, is formed by folding over the burred edges of a cut strip of metal to form rounded edges which, together with at least a part of the non-folded outer surface, are provided with an insulating covering. The preferred conductor comprises an aluminium foil strip with a coating formed by anodizing after folding, the coating extending around both edges and continuing across the unfolded outer surface. It may be formed by feeding the cut strip from a roll 30 through folding rolls 31 which fold the edges inwards and then through an ironing roll (not shown) which flattens the folded strip. It is then fed over guide roller 32 which directs it into tight engagement with an electrolytic roller 33 rotating in an electrolytic bath 34 containing e.g. a 15-18% aqueous solution of sulphuric acid. The roller 33 has a specially formed and partly masked surface (Fig. 7 and 8, not shown) so that only that part of the conductor which is to be anodized is in contact with the solution, and a plurality of suitably shaped cathodes 36 are provided. Suitable current densities and treatment times are given in the Specification. The strip then passes through a rinsing tank 51, a hot water sealing tank 52, and a pressurized-steam-sealing container 53, being finally fed by drive rolls 54 on to a storage spool 55.
